Description

【０００１】
【発明の属する技術分野】
本発明は、例えば自動車やオフィス用椅子など、環境温度が高温であったり、長時間着座する場合においても、快適な着座感を得ることができる椅子に関するものである。
【０００２】
【従来の技術】
従来のこの種の空調座席装置としては、図１５に示すようにシート本体の人体背面部が当接する部分に相当する部分の表皮クロス２を通して外気を強制的に吸気する空気袋３を前記シート本体に内蔵し、且つ前記空気袋３が吸気した外気を除湿乾燥して前記空気袋を通して人体背面部に排気する冷却除湿器４と加熱乾燥器５からなる除湿乾燥装置６をヘッドレストに内蔵して前記除湿乾燥装置６と空気袋を吸気通気路７、排気通気路８で連通させた構成になっている（特許文献１参照）。
【０００３】
上記構成において、人体背面の外気（３２℃、湿度８０％）は表皮クロスを通して空気袋３に吸気され、吸気通気路７を通して冷却除湿器４に入り冷却除湿（結露）され（１５℃、１００％）の空気となり、加熱乾燥器５に送られ加熱乾燥され（３０℃、５０％）の空気となり、排気通気路を通して空気袋に入り、表皮クロスから人体背面部に向けて吹出させ、冷却風による体温の奪われを防止しつつ蒸れ発生を防止する。しかし、上記従来の構成では、除湿において冷却除湿器で除湿を行うため、結露水を流すための排水管が必要になり自動車用本体に特別な加工を必要であり、また移動可能なオフィス用椅子としては簡単に使用できない。また、本体の熱容量が大きく、即効性がない。
【０００４】
また、吸湿材料を使用した空調座席装置としては、図１６、図１７、図１８に示すように、背もたれ部９は内部に空気通路１０を有しており、背もたれ部９と空気通路１０の間には水蒸気分圧の勾配にしたがった非通気性と透湿性を併せ持った透湿層１１が配置されており、空気通路１０には背もたれ部９から透湿してくる水蒸気が流れ込む。そして吸湿性材料を備えた空気乾燥装置１２を通して乾燥させた空気を空気通路１０に流すことで透湿層１１が背もたれ部外側にある水蒸気を透過させ、このとき水蒸気は乾燥した空気の中で蒸発する。なお、空気乾燥装置１２は、図１７に示すように、１５、１６は空気入口１７，１８を持ったゼオライトやシリカゲルのような吸湿材料で満たされた反応容器であり、それぞれ一体化された電気ヒーター２１，２２を有し、電気駆動される空気フラップ１４で空気通路１０入口と接続されている空気出口２０、および車室に開口した空気出口１９に流路が切り替えられるようになっている（特許文献２参照）。
【０００５】
上記構成において、空気乾燥装置１２を連続運転するために２つの反応容器１５，１６は交互に吸湿プロセス、ならびに再生プロセスと切り替えられる。一方の反応容器１５がヒーター２１で再生されている時（再生プロセス）、他の反応容器１６がその内部を流れる空気を吸着材料の吸湿作用によって乾燥させるとともに、吸着熱で空気の温度を加熱する（吸湿プロセス）。反応容器１６の吸着材が飽和すると、空気フラップを破線のように切り替えヒーター２２を通電し反応容器１６を再生するとともに反応容器１５がその内部を流れる空気を吸着材料の吸湿作用によって乾燥させる。また図にしめすようにファン２３を空気出口１９近傍に配設してもよい。しかし、上記従来の構成では、人体で発生した汗は椅子と接した所以外は吸収されず、また、衣類と透湿層を通して水分を吸収するために、汗の吸収量が少ない。また空気乾燥装置を出た空気は吸着熱で温度が高くなっているため、そのまま背もたれ部から吹出しても冷涼感は得られない。
【０００６】
また、吸着材を用いて連続的に吸着再生を行うユニットとして、図１９に示すような、コルゲートまたはハニカム形状に成型された円筒状の吸着材２４が知られており、空気の湿度を調節する調湿装置等に利用されている（特許文献３参照）。吸着材２４はタイミングベルト２５を介して駆動モーター２６でゆっくり回転しており、再生ファン２７によって送られた空気は再生用加熱ヒーター２８で高温に加熱された吸着材に送られ、吸着材に吸着していた水分を脱着し、湿り空気２９として排出される。そして水分が脱着した吸着材２４は回転し、送風ファン３０によって送られた高湿空気を送風する位置に移動し、高湿空気は除湿吸着材内へ導入され、水蒸気が吸着され、乾燥空気３１として排出され構成となっており、連続して高湿空気の除湿を行うことができるものである。しかし、上記従来の構成では、脱着している部位の吸着材熱が、除湿している部位に伝わるので乾燥空気温度が高くなり、乾燥空気によって、冷涼感を得るような装置には不適である。また、加熱ヒーターで高温に加熱した空気によって間接的に吸着材を加熱する構成のため、吸着材の加熱効率が低く、消費電力が大きい。また、吸着材に伝わらなかった熱は高温の湿り空気がとして大量に排出されるため室内の温度が上昇し、冷涼感を得るような装置には不適である。さらに風路が複雑であり、吸着材を回転させる構成が必要であり、吸着材も大きくなるので装置の小型化が難しかった。
【０００７】
本発明は上記課題を解決するため、結露水の処理が必要なく、除湿空気で人体を直接冷却するので、室温が高い場合に着座しても、すぐに冷涼感の得られる空調座席装置の実現を目的としたものである。

【課題を解決するための手段】
前記従来の課題を解決するために、本発明の空調座席装置は、空気を除湿するシリカゲルや活性アルミナなどの吸着材からなる除湿手段と前記除湿手段に室内空気を送風するシロッコファン等の除湿風送風機と、座席本体の表皮に設けられた除湿後の空気を噴出する噴出口と、噴出口に空気を送風するシロッコファン等の送風機と、除湿手段を輻射または熱伝導で加熱する電気ヒーター等の加熱手段からなる空調ユニットを持った構成としたものである。上記構成において、例えば夏季の炎天下であると、駐車中の車室内は室温が３５℃以上に上昇し、表皮は６０℃程度に上昇するが、ドライバーが乗車し空調座席装置を運転開始すると、まず除湿風送風機が駆動する。送風機によって０．２ｍ^３／分の流量で除湿手段に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。
高温低湿度の空気は、除湿手段から噴出口に導く通風路で座席本体に放熱し、（３７℃、２０％ＲＨ）の低湿度空気となって噴出口から吹き出し、人体背側面を流れる。その際体表面の汗を気化させることで急速に気化熱をうばい、乗車直後の人体に冷涼間を与える。車室内の空気はエアコンの駆動により、約３分後に冷風（２５℃、４０％ＲＨ）が送風され始めるので、除湿風送風機を停止して、送風機を駆動し噴出口から車室内の空気を送風することで、汗によるムレ感を防止する。また送風機を駆動している間に、加熱手段に通電し吸着材の温度を上昇させることで除湿手段に吸着した水蒸気を脱離させ、本体外へ放出させる。以上説明したように、本発明によって夏季に駐車中の暑い座席に座っても、すぐに冷涼感が得られ、また長時間座った場合でも、ムレ感を防止することが出来る。
【００１０】
【発明の実施の形態】
本発明の請求項１にかかる空調座席装置は、空気を除湿するシリカゲルや活性アルミナなどの吸着材からなる除湿手段と前記除湿手段に室内空気を送風するシロッコファン等の除湿風送風機と、座席本体の表皮に設けられた除湿後の空気を噴出する噴出口と、噴出口に空気を送風するシロッコファン等の送風機と、除湿手段を輻射または熱伝導で加熱する電気ヒーター等の加熱手段からなる空調ユニットを持った構成としたものである。
【００１１】
上記構成において、夏季の炎天下、駐車中の車室内は室温が３５℃以上に上昇し、表皮は６０℃程度に上昇するが、ドライバーが乗車し空調座席装置を運転開始すると、まず除湿風送風機が駆動する。除湿風送風機によって０．２ｍ^３／分の流量で除湿手段に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は、除湿手段から噴出口に導く通風路で座席本体に放熱し、（３７℃、２０％ＲＨ）の低湿度空気となって噴出口から吹き出し、人体側面を流れる。その際体表面の汗を気化させることで急速に気化熱をうばい、乗車直後の人体に冷涼間を与える。車室内の空気はエアコンの駆動により、約３分後に冷風（２５℃、４０％ＲＨ）が送風され始めるので、除湿風送風機を停止して、送風機を駆動し噴出口から車室内の空気を送風することで、汗によるムレ感を防止する。
【００１２】
本発明の請求項２にかかる空調座席装置は、空気を除湿するシリカゲルや活性アルミナなどの吸着材からなる除湿手段と前記除湿手段に室内空気を送風するシロッコファン等の除湿風送風機と、着座時に人体の汗発生が多い部位が接する位置に設けられた除湿後の空気を噴出する除湿風噴出口と、室内の空気を送風するシロッコファン等の送風機と、送風機からの風を人体に噴出する噴出口と、除湿手段を輻射または熱伝導で加熱する電気ヒーター等の加熱手段からなる空調ユニットを持った構成としたものである。
【００１３】
上記構成において、夏季の炎天下、駐車中の車室内は室温が３５℃以上に上昇し、表皮は６０℃程度に上昇するが、ドライバーが乗車し空調座席装置を運転開始すると、まず除湿風送風機が駆動する。除湿風送風機によって０．２ｍ^３／分の流量で除湿手段に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は、除湿手段から噴出口に導く通風路で座席本体に放熱し、（３７℃、２０％ＲＨ）の低湿度空気となって除湿風噴出口から吹き出し、発汗で濡れた人体、および衣類を流れる。その際汗をかく部位に集中して設けられた噴出口からの除湿風が、体表面の汗を気化させることで急速に気化熱をうばい、乗車直後の人体に冷涼間を与える。車室内の空気はエアコンの駆動により、約３分後に冷風（２５℃、４０％ＲＨ）が送風され始めるので、除湿風送風機を停止して、送風機を駆動し噴出口から車室内の空気を送風することで、人体側面の汗によるムレ感を防止する。
【００１４】
本発明の請求項３にかかる空調座席装置は、請求項請求項１、２の構成に加え、除湿手段で除湿後の空気を車室内空気で冷却する熱交換器を設けた構成としたものである。
【００１５】
上記構成において、夏季の炎天下、駐車中の車室内は室温が３５℃以上に上昇し、表皮は６０℃程度に上昇するが、ドライバーが乗車し空調座席装置を運転開始すると、まず除湿風送風機が駆動する。送風機によって０．２ｍ^３／分の流量で除湿手段に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は、熱交換器に導かれ車室空気で冷却され（３７℃、２０％ＲＨ）の低湿度空気となって噴出口から吹き出し、人体側面を流れる。
その際体表面の汗を気化させることで急速に気化熱をうばい、乗車直後の人体に冷涼間を与える。熱交換器によって除湿手段を出た高温低湿度の風が定常的に冷却されるので、長時間除湿運転を行うことが出来る。
【００１６】
本発明の請求項４にかかる空調座席装置は、請求項１ないし請求項３記載の構成において、加熱手段の運転中は送風機を駆動し、除湿手段を再生する構成としたものである。
【００１７】
上記構成において送風機を駆動している間に、加熱手段に通電し吸着材の温度を上昇させることで除湿手段に吸着した水蒸気を脱離させ、本体外へ放出させるので、除湿手段の再生中も人体を快適に保つことができる。
【００１８】
本発明の請求項５にかかる空調座席装置は、請求項１ないし請求項４記載の構成において、除湿風送風機の送風量は、運転開始直後が多い構成としたものである。着座直後はシートが６０℃程度あり、室温も高いので、大風量の除湿風を送風することで急速に冷涼感を得ることができる。またシート温度が下がってきたら、除湿風送風機の送風量を下げても冷涼感が得られる。したがって除湿手段の容量を小さくすることができ、除湿ユニットを小型化することができる。
【００１９】
本発明の請求項６にかかる空調座席装置は、請求項１ないし請求項４記載の構成に加え、車室内や、エアコン噴出口等の温度を検出する温度検知手段を持ち、温度検知手段の出力に応じて除湿送風手段の送風量を制御する構成としたものである。上記構成において、夏季の駐車後に着座する場合等で室温等が高い場合、温度検知手段の温度が設定値以上の場合、除湿風送風機の送風量を多くし、大風量の除湿風を送風することで急速に冷涼感を得ることができる。またエアコンの噴出温度や室温、シート温度が下がってきたら、少ない送風量でも冷涼感が得られるので、除湿風送風機の送風量を下げ、また送風機に運転を切り替える。したがって除湿手段の容量を小さくすることができ、除湿ユニットを小型化することができる。
【００２０】
本発明の請求項７にかかる空調座席装置は、請求項１ないし請求項６記載の構成に加え、着座者検知手段を持ち、着座者検知手段によって、空調ユニットの運転を開始する構成としたものである。着座者検知手段によって、ドライバーの自動車への接近、あるいは乗車、あるいはシートへの着座を検知すると、加熱手段に通電し吸着材の温度を上昇させ除湿手段に吸着した水蒸気を脱離させ、本体外へ放出させる。そして、その後、空調ユニットの運転を開始し、除湿風送風機を運転して除湿風を噴出口から人体に送ることで冷涼感を与える。したがって除湿手段の能力を最大にして空調ユニットを運転できるので、除湿能力が大きく、着座直後に大きな冷涼感を得ることができる。
【００２１】
本発明の請求項８にかかる空調座席装置は、請求項７記載の構成において、着座者検知手段をドア施錠検知手段としたものである。運転者が乗車する場合、まず、ドアを開錠するので、その信号を検知して、加熱手段を駆動させ除湿手段を再生し、除湿風送風手段を駆動することで着座直後に大きな冷涼感を得ることができる。
【００２２】
本発明の請求項９にかかる空調座席装置は、請求項７記載の構成において、着座者検知手段をドア開閉検知手段としたものである。運転者が乗車する場合、ドアを開くので、その信号を検知して、加熱手段を駆動させ除湿手段を再生し、除湿風送風手段を駆動することで着座直後に大きな冷涼感を得ることができる。
【００２３】
本発明の請求項１０にかかる空調座席装置は、請求項７記載の構成において、着座者検知手段をエンジン始動検知手段としたものである。運転者が運転を開始する場合、エンジンを始動させるので、その信号を検知して、加熱手段を駆動させ除湿手段を再生し、除湿風送風手段を駆動することで着座直後に大きな冷涼感を得ることができる。
【００２４】
本発明の請求項１１にかかる空調座席装置は、請求項７記載の構成において、着座者検知手段を着座検知手段としたものである。運転者がシートに着座すると、その信号を検知して、加熱手段を駆動させ除湿手段を再生し、除湿風送風手段を駆動することで着座直後に大きな冷涼感を得ることができる。

【実施例】
以下、本発明の実施例について図面を用いて説明する。

【００２７】
シート本体４０の座部４１、背部４２の内部に空気を除湿するシリカゲルや活性アルミナなどの吸着材からなる除湿手段４４と、除湿手段の入口を密閉する除湿手段入口風路切替手段５０と、除湿手段の出口を密閉する除湿手段出口風路切替手段５１と、前記除湿手段に室内空気を送風するシロッコファン等の除湿風送風機４５と、座席本体の表皮４３に設けられた除湿後の空気を噴出する噴出口４６と、噴出口４６に空気を送風する吹出口が噴出口向きに取り付けられたシロッコファン等の送風機４７と、除湿手段を輻射または熱伝導で加熱する電気ヒーター等の加熱手段４８からなる空調ユニット５２を持った構成としたものである。
上記構成において、駐車中等のスタンバイモードでは、除湿手段入口風路切替手段５０と、除湿手段出口風路切替手段５１は閉じる状態になっており吸着手段の除湿能力は保たれている。夏季の炎天下、駐車中の車室内は室温が３５℃以上に上昇し、表皮は６０℃程度に上昇するが、ドライバーが乗車し空調座席装置を運転開始すると、まず図４に示すような除湿モードとなる。除湿手段入口風路切替手段５０と、除湿手段出口風路切替手段５１は開く状態にし、除湿風送風機４５が駆動し０．２ｍ^３／分の流量で除湿手段４４に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は除湿手段４４の吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は、除湿手段４４から噴出口４６に導く通風路で座席本体に放熱し、（３７℃、２０％ＲＨ）の低湿度空気となって噴出口４６から吹き出し、人体背側面を流れる。その際体表面の汗を気化させることで急速に気化熱をうばい、乗車直後の人体に冷涼間を与える。車室内の空気はエアコンの駆動により、約３分後に冷風（２５℃、４０％ＲＨ）が送風され始めるので、再生／送風モードに切替る。除湿手段入口風路切替手段５０は開く状態にし、除湿手段出口風路切替手段５１は閉じる状態にし、除湿風送風機を停止して、送風機４７を駆動し噴出口４６からし０．６ｍ^３／ｍｉｎの風量で、室内の空気を送風することで、汗によるムレ感を防止する。また送風機４７を駆動している間に、加熱手段４８に通電し除湿手段４４の吸着材の温度を上昇させることで除湿手段４４に吸着した水蒸気を脱離させ、吸込口６４から本体外へ放出させる。また、除湿手段の再生が終了すると、送風モードに切替る。除湿手段入口風路切替手段５０と、除湿手段出口風路切替手段５１は閉じる状態にし、加熱手段を停止し、送風機を駆動し室内の空気を送風することで、汗によるムレ感を防止する。
【００２８】
以上説明したように、本発明によって夏季に駐車中の暑い座席に座っても、すぐに冷涼感が得られ、また長時間座った場合でも、ムレ感を防止することが出来る。
【００２９】
なお、室温を検知する温度検知手段５８と、着座者検知手段５９としてエンジン始動検知手段を設け、除湿風送風機４５、送風機４７、加熱手段４８、冷却風送風機４９、制御手段６０が除湿手段入口風路切替手段５０、除湿手段出口風路切替手段５１を制御する構成では、図６に示すようにエンジン始動検知手段がエンジン始動を検知すると、空調ユニットをスタートさせ、まず除湿モード運転を行う。除湿手段入口風路切替手段５０と、除湿手段出口風路切替手段５１は開く状態にし、除湿風送風機４５が駆動し０．４ｍ^３／分の流量で除湿手段４４に送り込まれた車室内の空気（３５℃、５５％ＲＨ）は除湿手段４４の吸着材で水蒸気を吸着され湿度が低下するとともに吸着熱で発熱し（６５℃、３％ＲＨ）の空気となる。高温低湿度の空気は、除湿手段４４から噴出口４６に導く通風路で座席本体に放熱し、（３７℃、２０％ＲＨ）の低湿度空気となって噴出口４６から吹き出し、人体背側面を流れる。その際体表面の汗を気化させることで急速に気化熱をうばい、乗車直後の人体に冷涼間を与える。車室内の空気はエアコンの駆動により、約３分後に冷風（２５℃、４０％ＲＨ）が送風され始めるので、温度検知手段によって室温が設定値の２５℃に低下すると除湿風送風機４５の送風風量を０．２ｍ^３／分に落とす。室温が低下しているので風量を落としても十分な冷涼感が得られる。したがって除湿手段の容量を小さくすることができ、除湿ユニットを小型化することができる。
【００３０】
なお、着座者検知手段として、キーレスエントリーシステム等を含むドア施錠検知手段や、ドア開閉検知手段、着座検知手段とした構成では、エンジン始動前にドライバーの自動車への接近、あるいは乗車、あるいはシートへの着座を検知すると、加熱手段４８に通電し吸着材の温度を上昇させ除湿手段に吸着した水蒸気を脱離させ、本体外へ放出させることができる。そして、その後、空調ユニット５２の運転を開始し、除湿風送風機４５を運転して除湿風を噴出口４６から人体に送ることで冷涼感を与える。したがって除湿手段の能力を最大にして空調ユニットを運転できるので、除湿能力が大きく、着座直後に大きな冷涼感を得ることができる。また、これらの着座者検知手段を複数種類同時に設けることで、より確実に運転する人、乗車する人、着座する人を検知することが可能となり、空調ユニットの運転開始を行い、快適な座席環境を実現できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a chair that can provide a comfortable seating feeling even when the user sits for a long time, such as an automobile or an office chair, when the ambient temperature is high or when the user sits for a long time.
[0002]
[Prior art]
As a conventional air-conditioning seat device of this type, as shown in FIG. 15, an air bag 3 forcibly sucking outside air through a skin cloth 2 in a portion corresponding to a portion of the seat body contacting the back of the human body is provided. And a dehumidifying / drying device 6 including a cooling / dehumidifying device 4 and a heating / drying device 5 for dehumidifying and drying the outside air taken in by the air bag 3 and exhausting the air to the back of the human body through the air bag. The dehumidifying and drying device 6 and the air bag are configured to communicate with each other through an intake air passage 7 and an exhaust air passage 8 (see Patent Document 1).
[0003]
In the above configuration, outside air (32 ° C., humidity 80%) on the back of the human body is sucked into the air bag 3 through the skin cloth, enters the cooling dehumidifier 4 through the intake air passage 7, and is cooled and dehumidified (condensed) (15 ° C., 100%). ), Which is sent to the heating / drying device 5 to be heated and dried (30 ° C., 50%), enters an air bag through an exhaust air passage, blows out from the skin cloth toward the back of the human body, and generates cooling air. Prevents stuffiness while preventing deprivation of body temperature. However, in the above-described conventional configuration, since dehumidification is performed by a cooling dehumidifier in the dehumidification, a drain pipe for flowing dew condensation water is required, and special processing is required for a vehicle body, and a movable office chair is required. Not as easy to use. In addition, the heat capacity of the main body is large and there is no immediate effect.
[0004]
Further, as an air-conditioning seat device using a moisture absorbing material, as shown in FIGS. 16, 17, and 18, the backrest portion 9 has an air passage 10 therein, and the space between the backrest portion 9 and the air passage 10 is provided. A moisture permeable layer 11 having both non-breathability and moisture permeability according to the gradient of the partial pressure of water vapor is disposed in the air passage 10, and the vapor permeable from the backrest 9 flows into the air passage 10. Then, the air dried through an air drying device 12 provided with a hygroscopic material is passed through the air passage 10 so that the moisture permeable layer 11 allows the water vapor outside the backrest to permeate. At this time, the water vapor evaporates in the dried air. I do. As shown in FIG. 17, the air drying device 12 is a reaction vessel 15 and 16 having air inlets 17 and 18 and filled with a moisture absorbing material such as zeolite or silica gel. It has heaters 21 and 22, and the flow path is switched to an air outlet 20 connected to the air passage 10 inlet by an electrically driven air flap 14 and an air outlet 19 opened to the vehicle interior ( Patent Document 2).
[0005]
In the above configuration, in order to continuously operate the air drying device 12, the two reaction vessels 15, 16 are alternately switched to a moisture absorption process and a regeneration process. When one of the reaction vessels 15 is being regenerated by the heater 21 (regeneration process), the other reaction vessel 16 dries the air flowing through the interior thereof by the moisture absorbing action of the adsorbing material, and heats the air with the heat of adsorption. (Hygroscopic process). When the adsorbent in the reaction vessel 16 is saturated, the air flap is switched as shown by the broken line, the heater 22 is energized to regenerate the reaction vessel 16, and the air flowing through the reaction vessel 15 is dried by the moisture absorbing action of the adsorbent material. Further, the fan 23 may be disposed near the air outlet 19 as shown in FIG. However, in the above-described conventional configuration, the sweat generated in the human body is not absorbed except at the portion in contact with the chair, and the amount of sweat absorbed is small because water is absorbed through the clothing and the moisture permeable layer. Further, since the temperature of the air that has exited the air drying device is high due to the heat of adsorption, a cool feeling cannot be obtained even if the air is blown out from the backrest as it is.
[0006]
Further, as a unit for continuously performing adsorption regeneration using an adsorbent, a cylindrical adsorbent 24 formed into a corrugated or honeycomb shape as shown in FIG. 19 is known, and adjusts the humidity of air. It is used for humidity control devices and the like (see Patent Document 3). The adsorbent 24 is slowly rotated by the drive motor 26 via the timing belt 25, and the air sent by the regenerating fan 27 is sent to the adsorbent heated to a high temperature by the regenerative heater 28, and adsorbed on the adsorbent. The removed moisture is desorbed and discharged as moist air 29. Then, the adsorbent 24 to which the moisture has been desorbed rotates and moves to a position where the high-humidity air sent by the blower fan 30 is blown, and the high-humidity air is introduced into the dehumidification adsorbent, where water vapor is adsorbed and the dry air 31 And can continuously dehumidify the humid air. However, in the above-described conventional configuration, the heat of the adsorbent at the desorbed portion is transmitted to the dehumidified portion, so that the temperature of the dry air becomes high, and the dry air is not suitable for an apparatus that obtains a cool feeling. . In addition, since the adsorbent is indirectly heated by air heated to a high temperature by the heater, the heating efficiency of the adsorbent is low and the power consumption is large. Further, heat that is not transmitted to the adsorbent is discharged in large quantities as high-temperature humid air, so that the temperature in the room rises and is not suitable for an apparatus that obtains a cool feeling. Further, the air passage is complicated, a configuration for rotating the adsorbent is required, and the adsorbent becomes large, so that it has been difficult to reduce the size of the apparatus.
[0007]
The present invention solves the above-described problems, and does not require the treatment of dew condensation water, and directly cools the human body with dehumidified air. Therefore, even when seated at a high room temperature, realization of an air-conditioning seat device that can immediately obtain a cooling feeling. It is intended for.
